Request: Metric Modulations

Hi guys,

I’m finishing up writing a string quartet, and in some of the link section I have metric modulations to move between each section. And somehow there is now way to do this? Or at least that I can find?

I’ve just been copying and pasting things from the font file into a text box to make it look nice, and to be honest this experience is not enjoyable. Any help would be greatly appreciated.

Go to the Tempo section of the right panel (in Write mode) and scroll down to the bottom. You’ll find the Tempo Equation section. Alternatively type Shift-T and then whatever equation you want, e.g. Shift-T e. = q

Hi, thanks for the quick response. So for more complicated equations, such as a triple q=q? or even more complicated questions such a quintuplets? Am I just missing something

You’re not missing anything. These are currently not really supported. @fkretlow’s free Metrico font is really useful for these; see GitHub - fkretlow/metrico: Font for metric equations in music notation.

Thanks for the help! Let’s hope this becomes baked into the Dorico experience at some stage.

Still no option to display a swing metric modulation (eights to triplets) in Dorico 4? Is this so hard to implement?

Well I suppose the reason is that there are workarounds for this at the moment, so it is doable. On the other hand the team is working hard on things that cannot be done or are bugged.

Without wanting to sound pointed… the fact that something so common isn’t yet implemented is surely because it’s more complicated than might appear.

Anyways, it would be semantic, which is a whole category of functionality.

It’s not a matter of difficulty, but of priority. Everyone has their own pet feature they think is absolutely necessary. The Team have their own list, which gets added to every week, and they will get to things in their own order.

Does anyone know how to have a metric modulation over the barline, followed by a new tempo indication? One seems to cancel the other out for me, and I’m not sure if I’m just missing something.

I’m trying to write something like this:

You cannot have both at the same grid position, so offset one slightly and adjust its location in Engrave.

When you say offset slightly, do you mean you need to create and then hide notes/rests to attach them to? It’s hard to understand why Dorico hasn’t yet made this possible more easily.

No, just move the caret to a different place and invoke shift-T

It is irrational to have two conflicting tempi at the same place. Which one should playback obey?

Ok great. That is helpful.

I hear what you’re saying about it being irrational. But in my case, it’s not. There are several indications that use shift+T and are related to tempo, but they are complementary, not conflicting.

Where does it say that the tempi in his image are conflicting? It’s a rit. that flows into a new tempo where the beat equals 52, which coincides with a metric modulation. This is a common occurence and there is nothing conflicting about it.

Exactly. Neither you, I, or Dorico knows. The rit will reduce the original tempo. Dorico will take that final tempo and double it for the tempo equation (it will not take the original tempo) and at the same time try to make h=52. Who will win?

Dorico does not know that it does not know at all, so the outcome will depend on the Dorico’s internal programming. And in principle it could depend also on other factors, so that in different configurations the outcome is different.
However “irrational” is very offensive. Please moderate your tone, sir.
The best thing to do is separate the two commands, of course, but if they are not contradictory the result could be the same even if they are in the same place.
The person who asked clearly wants that the transition happen, Dorico will make it happen, the order it is decided just inside the program, not necessary what one can envise.
The rit clearly will decrease until a certain value, then whatever this value is, the new tempo will take place.

That’s rich, coming from you!

Dorico does not allow more than one tempo event at any rhythmic position. So the issue does not arise.

Indeed, even if there are two different indications at the same position, they are forcibly processed in a certain order because of they are in a long list of internal events to be processed, and they are very close to each other (but not really coincident). So whatever little difference or hiccup is there, it lasts less than a microsecond, it is inaudible.
I do not bet on Dorico’s stability so it could crash (but I do not think), but I am referring to a common app behaviour.

(For the 3rd time) Dorico will not allow you to do this. So any debate is moot.
